Jordan L. Brenner, DDS

     Dr. Jordan Brenner was born in Boulder, CO and spent her childhood doing as much outside as possible. Hiking, camping, snowboarding, and running were and still are a few of her favorite activities. She moved to Cheyenne, WY in eighth grade and attended McCormick Junior High for two years, where she met her future husband Dr. Kegan. She graduated from Central High School in the spring of 2012 and started at the University of Wyoming that fall. Jordan enjoyed exploring Laramie and its’ surrounding attractions, volunteering in a neuroscience research lab, and being a member of Delta Delta Delta where she made many lifelong friends and learned a lot about leadership. 

     Dr. Jordan knew going into freshman year she wanted to do something in the medical field but did not officially decide on dentistry until the end of her sophomore year. After shadowing multiple physicians, she ended up shadowing her dentist she went to growing up, Dr. Gallagher. She quickly figured out dentistry was her true passion. She loved the private practice environment, where she felt you get the opportunity to not only help others and form relationships with your patients, but to also be a part of an incredible team. She noticed how well the staff worked together and felt that they really exemplified one of her favorite mottos – work hard, play hard. 

    She completed her undergraduate degree in 2016, where she received a BS in Physiology and minored in Chemistry and Honors. Immediately after, she attended Creighton University School of Dentistry and earned her D.D.S degree alongside Dr. Kegan. They enjoyed moving to Omaha and fell in love with all the city had to offer. The food, festivals, and endless community activities kept her more than busy when she wasn’t in class. At school she enjoyed getting to know professors, being a member of the American Student Dental Association (ASDA) and the American Association for Women Dentists (AAWD), and volunteering at school events to raise money for patients to receive free dental care. A highlight of her four years in Omaha was getting married during her junior year in Estes Park, CO! 

     Jordan has recently moved back to Cheyenne, WY and is happy to finally be home. She has two cats, Opie and Ziggy, and just adopted a puppy from Yola’s Pet Rescue named Rubicon. She is having fun visiting all of the new local shops and restaurants Cheyenne has to offer. She is really enjoying being part of the Alpine Dental team, something she has dreamed of since shadowing the practice years ago! She is a member of the American Dental Association and is currently attending an implantology maxicourse through the American Academy of Implant Dentistry (AAID). She is excited to see where her future here will lead her, and to have the opportunity to offer implant dentistry to the Alpine patient family in the near future.
